Sandtex® Microseal® masonry paint is microporous and provides sealing attributes that protect the coating against water ingress. This means that the coating allows the surface to breathe and moisture to evaporate whilst at the same time protecting the coated surface from water penetration. The advanced coating protects over an extended period against mould and algae growth. Its dirt resistant properties also help to maintain the coating’s aesthetic features, and with the benefit of being rainproof in just 1 hour* you can complete the job even if the weather forecast is not reliable. With 15 years trusted durability, you can ensure that your house looks better for longer.
